I am trying to setup a master-slave model of Arango. Able to do a first batch update but applier for live sync is not working. It keeps failing on indexing constraint which works perfectly fine in master and does not have a duplicate key issue.
require("@arangodb/replication").setupReplication({
...> endpoint: "tcp://master:8529",
...> username: “name”,
...> password: “pass”,
...> autoStart: true,
...> incremental:true,
...> verbose:true,
...> });
applier state.
{
"state" : {
"started" : "2020-12-08T07:21:50Z",
"running" : false,
"phase" : "inactive",
"lastAppliedContinuousTick" : null,
"lastProcessedContinuousTick" : null,

I tried (sync, async) everything. It is just doing the first batch update and live updates are not happening. Somehow applier is just shutting down. Please help
Can you try either
require("@arangodb/replication").setupReplication({
endpoint: "tcp://master:8529",
username: “name”,
password: “pass”,
autoStart: true,
incremental:true,
verbose:true,
includeSystem: true
});
for starting the applier on the current database, or, the following for starting the applier for all databases/the entire server
require("@arangodb/replication").setupReplicationGlobal({
endpoint: "tcp://master:8529",
username: “name”,
password: “pass”,
autoStart: true,
incremental:true,
verbose:true
});
In the latter case ( setupReplicationGlobal
) you can later check the state of the applier via
require("@arangodb/replication").globalApplier.state();
(mind the globalApplier
here vs. just applier
)
